Be it known that I, DAVID B.

Fig. 2 is asimilar viewof the opposite side of the same, and Fig. 3 is a perspective 'viewshowing the jack in positionto support the axle of a vehicle.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to wagon-jacks; and it consists in theimproved construction of a device of that class, as will be hereinaftermore fully described and claimed.

In the accompanying drawings, A denotes a piece of board or timber,which is cutoff on one side to form the incline B, having two steps oroffsets, O and D. Hinged upon this part A by means of the links E, F,and G is the movable part H, the under side of which is cut offslantingly, as shown at I, and provided with offsets J and K, adapted torest upon the shoulders G and D of the stationary part A, when themovable part H isin its raised or elevated position, for supporting awagon. The upper end of the part H is provided with a series of steps,L, M, and N, upon any one of which the wagon-axle may be placed, and isalso provided with a projec- 0 the links E, F, and G is the lever Iwhich 5 has its fulcrum upon the bolt Q, and is fastened to the movablepart H by means of the bolt B. By operating this lever it will be seenthat the movable part H may be raised or lowered; and when. lowered forthe purpose of lifting the movable part H up into its raised positionfor supporting the wagon-box this movable part will be supported uponthe shoulders or offsets O, D, and O of the fixed part or base-piece A.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States The combination, in a Wagon-jack, ofthe upright base A, having incline B, and steps or offsets O, D, and O,movable part H, having steps or offsets J, K, L, M, and N, hingelinks E,F, and G, lever P, and bolts Q and R, the whole constructed and combinedto operate substantially in the manner and for the purpose shown and setforth.

In testimony that I claim the foregoing as my own Ihave hereunto affixedmy signature in presence of two witnesses.
